A rider leads a horse train up the Bright Angel Trail. Exceptional landscape vistas draw millions of worldwide visitors to the South Rim of Grand Canyon National Park, Arizona, USA. Grand Canyon began forming at least 5 to 17 million years ago and now exposes a geologic wonder, a column of well-defined rock layers dating back nearly two billion years at the base. While the Colorado Plateau was uplifted by tectonic forces, the Colorado River and tributaries carved Grand Canyon over a mile deep (6000 feet / 1800 meters), 277 miles (446 km) long and up to 18 miles (29 km) wide.Add to Cart Add to Lightbox Download
